However if you place your own logo file inside the Koha installation 
(/usr/share/koha/opac/htdocs/opac-tmpl/bootstrap/images) the file may be 
deleted during the next update of Koha since Koha has the strange 
behavior not just to overwrite existing files but also to delete whole 
directories during an update (including all files inside - also files 
that you explictly saved under a new name because you changed the 
configuration).

Thus, as far as I know, it doesn't make much difference if you change 
the existing logo file or if you use your own logo file. You will have 
to restore the file after the next update either way.

Correct me if I'm wrong.

I have now added Marcs solution to the Koha Community wiki because many 
if not all libraries ask for this.
